PIPE-CARRIER FOUNDATION TOP.

Application filed March 14, 1924. Serial No. 699,368.

This invention relates to railway signalling appliances and more especially to appliances used in what is known as mechanical signalling and particularly to what are known as pipe carrier foundation tops.

The principal object of this invention is the provision of a pipe carrier foundation top which will be inexpensive to construct, install and maintain and that will require the smallest change in the number of parts regardless of whether used for a small number of pipe carriers or a large number, and will be so constructed that a maximum of standard stock rolled material may be used.

Other objects and advantages will appear as the description of the particular physical embodiment selected to illustrate the iinrention progresses, and the novel features of the invention will be particularly pointed out in the appended claims.

In describing the invention in detail and the particular physical embodiment selected to illustrate the invention, reference had to the accompanying; drawing, wherein, I have illustrated the particular preferred physical embodiment of my invention. and wherein like characters of reference designate corresponding parts throughout the several views, and in which:

Figure 1 is a perspective view of a pipe carrier foundation with improved pipe carrier foundation topattached thereto and several fragmentary pipe carriers shown as attached to and supported thereby; 2, is a cross sectional elevational view on the plane indicated by the line II--II of Fig. 1; Fig. 3, is a cross sectional plan view on the plane indicated by the line III III of Fig. 2; Figs. 4 and 5 are endand side elevational views respectively showing my improved pipe carrier foundation top attached to a style of foundation differing from that as shown in Fig. 1; Fig. 6, is a fragmentary view of a modified form of my foundation top.

A; is well understood by those skilled in the railway signalling art the so called functions, that is, the switches and signals positioned adjacent an interlocking tower are commonly operated by means of pipe lines worked from the tower manually. These pipe lines are supported and guided by what are known as pipe carriers. These pipe carriers are antifriction devices, com monly used and are well known in the railway signalling art, and serve to guide and support with the least possible amountof friction the pipe lines above mentioned.

These pipe carriers must be supported. A

common method of supporting these pipe carriers is to bolt them to a woodenplank of proper size which in turn is attached to two legs one at either end thereof, these two legs having a small plank attached to their other ends and all securely bedded in the earth. It is also common to use a concrete base in place of the attached legs or side brackets and lower plank. In such case the foundation may be used with various tops, that is, members which serve as means to which the pipe carriers themselves may be attached. 1

Applicants improvement is that of a pipe carrier foundation top which may be used in connection with any of the well known foundations either of the concrete type or of the double leg type. i v

In Fig. 1, numeral 1 designates a concrete foundation formed with corresponding and similarly located orifices as 2 in each side thereof suitable for receiving the inturned end of a hook bolt as 3. The book bolt passes upwardly and through a bracket as l.

Bracket 4 shown in detail in Fig. 2 Fig. 3 is formed by any of the well known and appropriate processes from, preferably, a portion of standard material such as fiat bar iron or steel. Such material is carried in stock by numerous firms and may at almost any time be bought in the open market in the desired quantities. The material is formed as shown particularly by Fig. 2 into what may be called a substantially widened U having the upper ends of thelegs of the U as at 5 and 6 formed into an overhang. The legs 7 and 8 are both formed with an orifice as 9 and 10 therein and the base 11 of the U is formed with three orifices therein 12, 13 and 14. The centralorifice 13 serves to receive the hook bolt 3 whereby when the nut 15, as shown by Fig. 1, is placed therein and turned to a firm bearing, the bracket 4 is held to the concrete foundation 1.

The bracket 4 positioned at the right hand end of the concrete foundation which as shown by Fig. 1, is constructed and arranged in all respects exactly as is the bracket 4 at the left hand end of Fig. 1. It of course is obvious that it is turned end for end as compared to the bracket shown on and in tion so as to bring the orifice 13 beyond the edge of the foundation. In order to complete the pipe carrier foundation top I use two strips 15 and 16 as it is shown in Fig. 1. These strips 15 and 16 are formed preferably as an angle strip or as commonly called an angle bar shown and are constructed preferably of the ordinary and well known angle iron or steel of commerce, as such material is carried in stock in large quantities by a considerable number of firms and may be purchased at almost any time in the open market. These strips 15 and 16 are formed .with orifices as 17. These orifices are placed apart a distance corresponding to the required spacing; of the pipe carriers when spaced the closest together that they may be spaced. it is my intention to manufacture these angle strips in lengths as great as may be conveniently worked upon and carried from place to place to the end that signal departments may stock tl'iese strips and then if they have pipe carrier foundations or tops to construct to carry these strips to the place where the foundations are tobe constructed and to then sever the required amount from such a length as will best suit their needs as governed by the number of pipecarriers needing support. These lengths, as 15 and 16, as best shown in Fig. 2, are held between the overhanging 130l. tions of the legs 7 and 8 and a bolt 18. If the nut 19 of the bolt 18 is properly tight ened it is obvious that the strips 15 and 16 will be tightly and rigidly held. a

The pipe carriers as 20 are attached by bolts 21 or other suitable means to the strips 15 and 16. The angle strips 15 and 16 form the immediate support for the pipe carriers proper and may be of any length desired, supported on the signal foundation and one or as many foundations may be used to support the strips 15 and 16 as is necessary, it being readily apparent that no parts other than those already described hereinbeiore are necessary to support the strips as 15 and 16 by one or any number of foundations.

From the above description it will now be understood that my pipe carrier foundation top is constructed of materials of such a nature that they are commonly held in stock in large quantities by numerous firms and does not consist or include parts either cast or malleableized so that in case of need the pipe carrier foundation to s of my iuvention may be quickly and readily proresales dueed without the delays incident to casting and malleableizing which. always requires several weeks and sometimes many weeks.

In Fig. 4 I have shown the application of my improved top to a type of foundation differing from that as shown by Fig. 1. In Figs. 4t and 5 the foundation is constructed of a lower plank 22 bolted by means of bolts as 23 and 2% to legs or brackets as 2- 1. and 25. These brackets at their upper ones contain orifices through which bolts, as 26 and 27 as shown by l, may be passed through the orifices as 12 and 1 1 of the bracket l. The members at and commonly have a plank connected to their upper ends just as the plank 22 connects their lower ends. Although applicant has not shown such plank Figs. 4 and 5 it not being absolutely necessary with applicants type of construction, nevertheless, it is desired to have it under" stood that applicant does not exclude the use of such a plank as commonly used in connection with his improved top.

Fig. 6 illustrates a modified form of my l acket in that instead of having a bolt as 18 extending across and through the legs of the U, I pass a bolt as 28 through one leg only of the bracket 29 and position a washer 30 on the bolt so that by setting up the bolt 1 engage the strip 16 with the washer and hold the strip firmly but frictionally.

Although I have particularly described the construction of one physical embodiment of invention and explained the operation and principle thereof, nevertheless, I desire to have it understood that the form selected is merely illustrative but does not exhaust the possible physical embodiment of the idea of means underlyin my invention.

What I claim as new and desire to secure by Letters Patent of the United States is:

In a pipe carrier foiuidation top in combination; substantially U shaped members formed with the extremity of each leg; slightly overhanging inwardly and formed with an orifice in each leg; a bolt passing! through the orifices in the legs of the U shaped members; angle members, one bearing' against each leg and held between the bolt and the overhang of a legr; said angle members formed with spaced orifices for receiving pipe carrier attachingmeans; and means for attaching; the U shaped member to a foundation.
